1) A solid sphere of diameter “x” cm is melted to make 54 solid congruent hemispheres of diameter
0.06 m, without using calculator and showing all
necessary steps find exact value of x.

2) Surface area of 100 congruent solid spheres of
diameter “y” m is same as total surface area of 300
congruent solid hemispheres of diameter 10cm ,
find the exact value of y.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
